Stress physiology is shaped by early experience, with enduring effects on health. The relation of chronic maternal physiological stress, as indexed by hair cortisol, to infants' stress systems and to mother-infant interaction quality has not been established. We examined maternal hair and salivary cortisol, six-month-old infants' salivary cortisol, and mother-infant interaction in 121 mother-in...

We studied the effect of age on the circadian rhythm of plasma cortisol in 34 normal subjects, aged 18-75 yr. Blood was sampled at 20-min intervals beginning at 2000 h, and the data were analyzed using the PULSAR program and the cosinor method. There was a negative correlation between age and the time of the maximum cortisol concentration (r = -0.548; P = 0.001), the time of the nadir cortisol ...

*Expected maximum >600 nmol/l. deficiency. The high cortisol concentration during his first admission suggested that there was no deficiency in production of glucocorticoids, only in mineralocorticoids, although the suboptimal rise during infusion of tetracosactrin indicated some loss of reserve cortisol. Postmortem studies have shown a high prevalence of adrenal disease in patients with AIDS. ...

A current hypothesis of ovine parturition proposes that fetal adrenal cortisol induces placental E2 production, which, in turn, triggers intrauterine PG production. However, recent evidence suggests that cortisol may directly increase PG production in trophoblast-derived tissues. To separate cortisol-dependent and estrogen-dependent PG production in sheep intrauterine tissues, we infused single...

BACKGROUND The physiological mechanism by which bulls stimulate resumption of ovarian cycling activity in postpartum, anovular, suckled cows after calving may involve the concurrent activation of the hypothalamic-hypophyseal-ovarian (HPO) axis and hypothalamic-hypophyseal-adrenal (HPA) axis. Thus, the objectives of this experiment were to determine if characteristics of temporal patterns of cor...

Cortisol concentration was estimated by a competitive protein-binding method in the lumbar cerebrospinal fluid (CSF) of patients suffering from depression or from mania, and compared with the CSF cortisol concentration of neurological control patients not suffering from an affective disorder. There were no significant differences between the groups.

introduction: ghrelin is a potent orexigenic agent in rodents and humans. some studies have shown that ghrelin participates in the adaptive response to weight loss and plasma concentration of ghrelin rises with dieting. on the other hand, weight loss and fasting is accompanied by increased levels of epinephrine and cortisol. in this study, we investigated the effects of epinephrine and cortisol...

Cortisol and creatinine were measured in two consecutive overnight urine collections from 103 healthy school children, ages seven to 18.5 years. Mean cortisol and creatinine concentrations were respectively 194 nmol/L and 12.7 mmol/L. The data were statistically analyzed to simultaneously assess any effects of sex, age, weight, day of collection, and urine volume. Mean urine volume for boys exc...

Hasiec M., Szlis M., Chmielewska N., Górski K., Romanowicz K., Misztal T. (2017): Effect of salsolinol on ACTH and cortisol response to handling stress in early anestrous sheep. Czech J. Anim. Sci., 62, 130–139. Inhibition of hypothalamic–pituitary–adrenal (HPA) axis activity by salsolinol was demonstrated in lactating sheep. We assessed whether salsolinol regulates, besides lactation, also adr...

this study examined the effects of implanted cortisol (to imitate chronic stress) on the hematological responses and cortisol values of female great sturgeon, huso huso, after an endoscopic operation. at the beginning of experiment, all the fish were examined using an endoscope to evaluate gonad development. then, in order to mimic chronic stress following surgery, capsules of cocoa?? butter co...
